feature: multiplexing support for database plugins (#14033)
* feat: DB plugin multiplexing (#13734)

* WIP: start from main and get a plugin runner from core

* move MultiplexedClient map to plugin catalog
- call sys.NewPluginClient from PluginFactory
- updates to getPluginClient
- thread through isMetadataMode

* use go-plugin ClientProtocol interface
- call sys.NewPluginClient from dbplugin.NewPluginClient

* move PluginSets to dbplugin package
- export dbplugin HandshakeConfig
- small refactor of PluginCatalog.getPluginClient

* add removeMultiplexedClient; clean up on Close()
- call client.Kill from plugin catalog
- set rpcClient when muxed client exists

* add ID to dbplugin.DatabasePluginClient struct

* only create one plugin process per plugin type

* update NewPluginClient to return connection ID to sdk
- wrap grpc.ClientConn so we can inject the ID into context
- get ID from context on grpc server

* add v6 multiplexing  protocol version

* WIP: backwards compat for db plugins

* Ensure locking on plugin catalog access

- Create public GetPluginClient method for plugin catalog
- rename postgres db plugin

* use the New constructor for db plugins

* grpc server: use write lock for Close and rlock for CRUD

* cleanup MultiplexedClients on Close

* remove TODO

* fix multiplexing regression with grpc server connection

* cleanup grpc server instances on close

* embed ClientProtocol in Multiplexer interface

* use PluginClientConfig arg to make NewPluginClient plugin type agnostic

* create a new plugin process for non-muxed plugins

* feat: plugin multiplexing: handle plugin client cleanup (#13896)

* use closure for plugin client cleanup

* log and return errors; add comments

* move rpcClient wrapping to core for ID injection

* refactor core plugin client and sdk

* remove unused ID method

* refactor and only wrap clientConn on multiplexed plugins

* rename structs and do not export types

* Slight refactor of system view interface

* Revert "Slight refactor of system view interface"

This reverts commit 73d420e5cd2f0415e000c5a9284ea72a58016dd6.

* Revert "Revert "Slight refactor of system view interface""

* only provide pluginRunner arg to the internal newPluginClient method

* embed ClientProtocol in pluginClient and name logger

* Add back MLock support

* remove enableMlock arg from setupPluginCatalog

* rename plugin util interface to PluginClient
